where b.max is the maximum size of feed is compression strength is modulus of elasticity is density of material of balls is inner diameter of the mill body generally, a maximum allowed ball size is situated in the range from to the degree of filling the mill with balls also influences productivity of the mill and milling efficiency.table of contentsoptimum size of ballstests with different mixtures of balls in conical, cylindrical, and grid millsclosed-circuit grinding several years ago, davis assumed that the rate of wear of the different sizes of balls in a ball mill was directly proportional to the weight of each ball, and he evolved a formula for calculating a balanced charge. operators have used this formula when
sep 01, 2013 for a single size of make-up ball, the mass fractions in the mill within the size ranges are calculated from: max min where and represent the upper and lower boundaries of the ball size interval max is the largest ball size in the mill, and min is the aug 14, 2017 ball mill consists of a horizontal revolving cylinder containing a charge of tumbling or cascading balls, pebbles or rods. As a very rough indication, ballrod charge may occupy 2550% of the total internal volume of the mill. the length-to-diameter ratio of such a cylinder usually is between and ball mills can perform wet or dry
